Gem Book

I believe Paul Deasy on shophq has one, and perhaps Michael Valattuti? That might give you a place to start.

jtv.com

It's jewelrytelevision.com - put gemstone books in their search bar and all their nice books come up.

Also, there is a tab on their site called 'learning center'. I wonder if you might find something of interest there.

"The Jeweler's Directory of Gemstones: A Complete Guide to Appraising and Using Precious Stones From Cut and Color to Shape and Settings" By Judith Crowe

The book is so much more then the title alludes, it's also perfect for a gemstone jewelry collector. You can find it at Amazon.

Re-reading the OP, It seems I overlooked the words "young grandson".

Although, the book I mentioned is a great resource for us older gem geeks.

Thanks so much ladies! I'll look into all them.

missbonbon, what a fun thing to get your grandson into!

I really like jtv's site, alot of learning tools, they even have a Jewel School show, it use to air on Sundays but not sure what they are doing now. If you find something you like there google 'jtv coupon' first, there are always free shipping codes and 10, 15, 20% off coupons out there.

Two excellent books I recommend:

Smithsonian Rock & Gem Book

Minerals and Gemstones: by: Dr. David C. Cook & Dr. Wendy L. Kirk

Both have wonderful descriptions and pictures.
